 The area of a circle is less than 1 dm². Find the radius of the circle. The area of a circle is less than 1 dm². Find the rad
Ipatiy [6.2K]
\bf \textit{area of a circle}\\\\
A=\pi r^2\qquad 
\begin{cases}
\textit{let's say the Area is 1 exactly}\\
A=1
\end{cases}\implies 1=\pi r^2
\\\\\\
\cfrac{1}{\sqrt{\pi }}=r

if you drop the radius to less than that, then the Area will also drop to less than 1 unit, in this case it happens to be a decimeter

25 is 45% of what number
Oksi-84 [34.3K]

Answer: 55.56

Step-by-step explanation:

Let the unknown number be k

(45 x k) / 100 = 25

45k/100 = 25

multiply both sides by 100

45k = 25 x 100

45k = 2500

divide both sides by 45

k = 2500/45

k = 55.56

Will give brainliest and 5stars and thank you if youre answer is right
slega [8]

Step-by-step explanation:

since

25⁰= 1 minute

x⁰ = 11 minutes

cross multiply

25 x 11= x

x= 275⁰

temperature after being turned on=275⁰

temperature after 11 minutes= 275⁰ + 75⁰= 350⁰

temperature(x) after being turned on

25tt=x

temperature (x) after minutes

x= 25tt + 75⁰

Put these numbers in order from least to greatest 12%, -1/2, 0, -0.22, 0.56
uysha [10]

Answer: -1/2, -0.22, 0, 12%, 0.56

Step-by-step explanation:

-1/2 is equal to -0.50, making it the number with the least value.

-0.22 is closer to 0 than -0.50, meaning it is greater then -0.50 and less than 0.

0 is between the negative and positive numbers, giving it the spot that it has.

12% is equivalent to 0.12, meaning it is more than 0, and less than 0.56, which is the greatest number.

0.56 has more value than any other number in the problem, meaning it goes last in the order.
